Clearblue Advanced Digital OPK

Alyssa • I recently lost my first pregnancy and am looking forward to trying again in a few months.
Hey all! This month I switched to using the Clearblue Advanced Digital. I have been testing the past 10 days and the last 4 mornings I tested and got the flashing "high" reading but no peak reading. Has anyone else had this happen? Do I need to just keep testing? I thought I would have seen a peak reading by now.
